controlling tab visibility based on work item's state

One answer

I'm developing a custom work item type and would like to control the
visibility of a tab based on the work item's state. Is this
possible? If so, how?
It is possible to hide attribute presentations based on state, but not
entire tabs.
Please see 'hideIfInState' described in
